Answer:
The answer to your question is a) y = 1.5x - 6
b) y = -4x + 6.1
c) Point (2.2, -2.7)
Step-by-step explanation:
First line Second line
P (0, -6) Q (1, -4.5) R (0, 6.1) S (1, 2.1)
m = (-4.5 + 6) / (1 - 0) m = (2.1 - 6.1) / (1 - 0)
m = 1.5 / 1 m = -4/1
m = 1.5 m = -4
Line Line
y - y1 = m(x - x1) y - 6.1 = -4(x - 0)
y + 6 = 1.5(x) y - 6.1 = -4x
y = 1.5x - 6 y = -4x + 6.1
Solve the system by equality
1.5x - 6 = -4x + 6.1
1.5x + 4x = 6.1 + 6
5.5x = 12.1
x = 12.1 / 5.5
x = 2.2
Find y
y = 1.5(2.2) - 6
y = 3.3 - 6
y = -2.7
Point (2.2, -2.7)
F(x) = 8x + 1
a) The slope is the number on the x which is 8
b) y-intercept is added (or subtracted) to the x which is 1
c) f(0) = 8(0) + 1 = 1
d) 9 = 8x + 1
8 = 8x
x = 1 - solution
(1, 9) - ordered pair
e)
-7 <= 8x + 1
-8 <= 8x
-1 <= x
{x | x => -1}
I'll let you graph f(x)
The formula for volume of a rectangular prism (baking pan) is L•W•H.
33cm•23cm•5cm= 3795cm^3
Answer:
You need to compare the two sets of strips. If one set is larger than the other, then the fractions are not equal.
